Abstract

L'invention concerne un procédé de communication de paquets radio permettant de transmettre en parallèle une pluralité de paquets radio au moyen d'une pluralité de canaux radio déterminés comme ouverts par détection de porteuse, de transmettre en parallèle une pluralité de paquets radio au moyen d'un multiplexage spatial faisant appel à un canal radio unique déterminé comme ouvert, ou de transmettre en parallèle une pluralité de paquets radio au moyen d'une combinaison de ces techniques. Ce procédé consiste à établir un canal indispensable nécessairement utilisé pour la transmission, et, à condition que le canal indispensable soit ouvert, à utiliser des canaux radio comprenant ce canal indispensable pour transmettre les paquets radio. En d'autres termes, dans le cas d'une transmission en parallèle d'une pluralité de paquets radio, on utilise des canaux radio comprenant le canal indispensable pour la transmission, la transmission n'étant pas possible si le canal indispensable n'est pas ouvert.
